Detailed Solution
Download Solution PDFGiven:
Length of rectangle = 2 × Breadth
Perimeter = 78 m
Formula used:
Perimeter = 2 × (L + B)
Area = L × B
Where L is length and B is the breadth
Calculation:
Let the breadth of the rectangle be x m and the length of the rectangle be 2x m
Perimeter = 2 × (2x + x) = 6x
⇒ 78 = 6x
⇒ x = 13 m
Length = 2 × 13 = 26 m and Breadth = 13 m
Area = L × B
⇒ Area = 13 × 26
∴ Area of rectangle is 338 m2
